During their 11-day mission the astronauts fitted the telescope with corrective optics and a new set of European solar panels. If all goes according to plan the observatory will be restored to very nearly its original capability. The first images from the rejuvenated telescope should be released in about 6-8 weeks.

ESA had a major role in this mission. In addition to providing the solar arrays, the European Space Agency helped NASA test the Costar corrective optics system. ESA astronaut Claude Nicollier operated the shuttle's robot arm throughout the complex spacewalks to service the telescope and during the crucial capture and release phases.

"This was a particularly important international mission from the standpoint of our Swiss and European Space Agency crew member Claude Nicollier, who played an incredibly important part in the repair of the Hubble Space Telescope", mission commander Dick told Swiss Minister of Internal Affairs Mrs Ruth Dreifuss, during a VIP telephone call on Sunday morning. "If there was an unsung hero of this mission it would be Claude and his arm because without them we could not have worked the way we did and been as successful as we were".
